  • A high performance liquid chromatographic method was developed for the determination of DA-6034 in biological fluids using fluorescence detector. The method involved deproteinization of biological sample with the same volume of acetonitrile, 0.2M zinc sulphate. and 0.15M barium hydroxide. The aliquot of supernatant was injected onto Nova-pak C18 column and detected by fluorescence detector. Emission and excitation wavelength of detector were 336nm and 440nm. (omitted)

  • Aspergillus fumigatus causes a variety clinical syndrome in lung including aspergilloma, chronic necrotizing aspergillosis, invasive pulmonary aspergillosis, and allergic bronchopulmonary aspergillosis. Aspergilloma develops by a colonization and growing of Aspergillus inside lung cavities with underlying lung disease. There is a few report of endobronchial aspergilloma without lung parenchymal lesion. We experienced a case of endobronchial aspergilloma did not fit any category of Aspergillus-induced lesion, who show minimal fibrostreaky denstities on chest PA and chest CT. Massive hemoptysis was improved by a removal of the aspergilloma in this patient. Here, we report a rare case of endobronchial aspergilloma showing massive hemoptysis with review of literatures.
